Choose a lingerie manufacturer with experience in your product category and development support that fits how far your brief has progressed. Ask how the team will review your design or reference, manage sampling and fit feedback, and carry approved materials and specifications into production. Before comparing quotes, make sure each supplier is working from the same product details and states its assumptions for quantity, materials, sample costs, timing, quality checks, and shipping.
Start With the Product Category
First, define the garment you need made. “Lingerie” covers products with different fit, material, and construction demands. A factory that makes basic underwear well is not automatically the right choice for a fuller-bust bra.
For a structured bra, the discussion should reach beyond appearance to the cup, wing, strap, underband, and closure. With panties, waistband and leg finishes may be central to the fit review. A shapewear brief brings different questions about intended fit, stretch, and construction. None of these can be answered by a broad product-category claim alone.
Relevant samples are more useful than a long catalogue. If your brief calls for a particular bra construction, look at work that relates to it and discuss what would have to change for your own design and size range.
Understand What the Factory Can Actually Develop
A tech pack with measurements and construction details gives a factory a different starting point from a physical sample. A sketch or product idea may still leave material, fit, and construction decisions open. Be clear about which of those decisions you expect the manufacturer to help resolve.
The route descriptions below follow Xinnishi’s published OEM/ODM process. They describe Xinnishi’s development routes, not universal definitions used by every manufacturer.
| Development Route | What the Buyer Provides | What the Factory Helps Confirm |
|---|---|---|
| OEM — buyer-defined specifications | What the Buyer ProvidesA tech pack, measurements, approved construction, or another defined product reference. Include the product category, target market, size range, known material or trim requirements, and estimated quantity. | What the Factory Helps ConfirmWhether the information is sufficient for technical review; feasibility of the proposed fit, construction, size range, and materials; and which details still need to be resolved. |
| ODM — development from an earlier brief | What the Buyer ProvidesA product idea, sketch, reference product, or market brief. Describe the intended customer, product function, target market, category, size range, estimated quantity, and which decisions are fixed or still open. | What the Factory Helps ConfirmThe product and material decisions still needed; feasibility of the proposed fit and construction; and the development scope and technical inputs required for the project. |
Quotation prompt: Before comparing quotes, confirm the MOQ basis, development and sample charges, material and packaging assumptions, payment and shipping terms, and sample timing separately from bulk timing.
Private Label: If you are considering private label, ask us to confirm whether it is available for your specific product and what branding, labeling, or packaging changes are possible. Do not assume a ready-stock range or standard private-label program.
Look Beyond the Finished Garment
A fabric can feel right on a swatch and behave differently in a garment. Stretch, recovery and handfeel interact with the lining, elastic, trims and the way each component is used in the construction.
Treat material choices as part of product development. Xinnishi’s fabric development page describes connecting material decisions with fit and construction before sampling. The sample review should then identify the actual materials used, so any later substitution can be assessed against the approved garment.
From Material Brief to Garment Sample
Xinnishi’s published fabric-development workflow describes a path from a product or material brief through fabric selection, sample evaluation, garment development and approval before bulk production. The page says stretch, recovery and handfeel are reviewed alongside fit, trims and construction, with approved material and garment requirements carried into production. For buyers, the useful starting point is to describe the fabric’s job, not only its fiber composition: note the intended handfeel, stretch, target weight where relevant, and planned garment structure. Review candidate fabric directions with the lining, elastic and other components they will be paired with, then evaluate the chosen direction in a garment sample before approving the material specification. That check can reveal when a preferred swatch does not suit the intended fit or feel before the production requirements are fixed.
Review the Sampling Process
Treat each sample as a review against the current brief, not as a general “looks good” check. Before reviewing it, identify the sample version, size, materials, and the questions this round is meant to answer.
For a lingerie sample, review three areas separately:
- Fabric and components: Check the identified fabric, lining, elastic, and trims against the brief. Assess handfeel and stretch or recovery where they matter to the product, and flag any substitution for review.
- Fit: Record the size reviewed, the relevant measurements, and what you observed when the garment is worn. For a bra, that may include cup coverage, band feel, or strap placement; for panties, rise, waistband, or leg opening, as relevant to the design.
- Construction: Check whether the sample follows the intended construction and finishing. Note the specific seam, elastic attachment, bonded edge, or seamless transition only when it applies to the style.
Make each revision comment specific: identify the sample version and location, describe the issue, and state the requested adjustment. Separate requested changes from confirmed decisions.
Before approving a sample for bulk production, link that approval to the exact sample version and the production requirements it represents: measurements and size range, fabric and trim references, construction, color, labels, packaging, and any agreed deviations. Confirm that both sides are using the same approved reference.
Sample Revision Record — buyer reference example
| Sample version | Issue identified | Requested adjustment | Approval status |
|---|---|---|---|
| Style A — V1 (illustrative only) | Issue identifiedFit review notes a tighter-than-intended band feel in the evaluated size. | Requested adjustmentReview the band measurements and elastic requirements; identify any agreed change in V2. | Approval statusPending V2 review — not approved for bulk. |
This is an illustrative buyer reference, not an Xinnishi customer case, internal record, or description of an existing company procedure.
Verify Manufacturing Capability
Start with the garment construction and production route it requires. In seamless development, equipment, fabric behavior—such as stretch and handfeel—and garment structure need to be considered together. Seamless knitting, sewing, bonding and laser cutting are distinct operations, though one design may combine them. Match each required operation to the factory’s equipment, product scope and documented production checks.
Check Quality and Compliance Documents
Review quality control against the approved garment. Material checks, pre-production confirmation, in-line review, final inspection and packing verification address different points in an order; the buyer should understand which requirements each check covers.
Certification and audit documents also answer different questions. Product standards, recycled-content documentation, facility environmental verification, social audits and chain-of-custody records are not interchangeable, and their relevance depends on the product and sourcing program.
Xinnishi’s public Quality & Compliance page links to documents for procurement review. The page’s list is a starting point, not confirmation that a particular document is current or applies to a specific order. Check the original file, holder, reference, scope and validity period against the product, site and program requirements before relying on it.
Clarify Commercial Conditions Early
A useful RFQ gives each manufacturer the same product brief to price. Before sending it, gather the details below and mark undecided items as open. Ask each supplier to state its assumptions, exclusions, and any details that could change the quotation.
| RFQ item | What the buyer prepares | What the manufacturer should confirm |
|---|---|---|
| Product and construction | What the buyer preparesProduct category, tech pack or reference, key construction details, and target market. | What the manufacturer should confirmWhether the information is sufficient for technical review, what is feasible, and which specifications are still needed. |
| Materials and sizing | What the buyer preparesFiber composition and fabric or trim requirements, if known; performance or handfeel priorities; size range and available measurement specifications. | What the manufacturer should confirmMaterial assumptions or alternatives, fit and construction questions, and any missing size or measurement details. |
| Quantity and MOQ | What the buyer preparesTotal quantity, broken down by style, color, and size where applicable. | What the manufacturer should confirmThe MOQ basis for the project—by style, color, or size where relevant—and any quantity assumptions that affect the price. |
| Sampling and development | What the buyer preparesCurrent development materials, requested changes, and what the sample needs to demonstrate. | What the manufacturer should confirmSample and development charges, what review or revision scope is included, expected sample timing, and what approval is needed before bulk-production timing can be confirmed. |
| Labels, packaging, and customization | What the buyer preparesBrand artwork or specifications, label and packaging requirements, and any requested customization. | What the manufacturer should confirmWhich requirements can be supported for the project, what information is still needed, and any related costs or exclusions. |
| Quotation and delivery | What the buyer preparesPreferred quote currency, delivery destination and requested timing; specify a delivery basis or Incoterm if your team uses one. | What the manufacturer should confirmQuote currency and validity, unit-price basis, included or excluded costs, payment and delivery terms, and the assumptions behind sample and bulk lead times. |
Compare quotations against the same product specifications, quantity breakdown, currency, delivery basis, and included scope. Record differences and open assumptions before comparing unit prices.
Evaluate Communication During Development
A productive development exchange is specific. The factory clarifies what it understood, identifies missing information or technical questions, and distinguishes confirmed decisions from open items. The buyer should respond to the same issue and sample version so both sides can see what has been resolved and what remains under review.
Ask for Evidence Before You Commit
The evidence should fit your garment and sourcing requirements. A relevant category sample, a clear account of the development work, an identified approval reference, and documents applicable to your order tell you more than a general assurance of capability. Some evidence will only be available after sampling; identify when it can be reviewed and who will approve it.
Final Manufacturer Comparison Checklist
Use the same brief when comparing suppliers. Record an evidence reference or an open question for each one, then compare scope and assumptions before unit price.
| Comparison item | Record for each supplier | Decision check |
|---|---|---|
| Product fit | Record for each supplierRelevant sample or reference; product and construction | Decision checkDoes the evidence match the intended garment? |
| Development route | Record for each supplierStarting brief, open technical decisions, each party’s role | Decision checkIs it clear who will resolve each open decision? |
| Sample and approval | Record for each supplierSample version, material/specification reference, approval status | Decision checkCan the approved sample be tied to the bulk requirements? |
| Quotation basis | Record for each supplierMOQ basis, quantity split, currency, included scope and delivery basis | Decision checkAre the quotations based on comparable assumptions? |
| Quality and documents | Record for each supplierChecks described; document title, holder, scope and validity to verify | Decision checkDoes the evidence apply to this product and program? |
| Communication and open items | Record for each supplierUnanswered questions, responsible contact and next agreed checkpoint | Decision checkAre dependencies and unresolved points visible? |
The aim is to compare how each supplier will handle your specific product, what evidence supports its proposal, and which commercial or technical questions remain open.
